The language of the art or the artistic expression of children is a given and innate expression ability - to communicate and shape. This ability develops from the natural potentials of the child’s being, in terms of a spontaneous interaction of the inner world of the child and its external environment. In order for the child to express itself spontaneously and transfer its imagination to paper, it needs a means of expression. In the art task that I worked on with children, the means of expression was colour. It is the basic means of expression in painting. The child expresses itself with colour through various techniques. This final thesis shall address all painting techniques with a particular emphasis on water-colour and tempera. Two activities have been carried out for the mentioned painting techniques with an older age group in the Ciciban kindergarten in Otočac. The tempera technique was used in the first activity. The topic was: the parts of the City of Otočac. The children painted with examples of photographs but were also given the freedom to perceive some details by memory and insert them into the painting. The other activity was with water-colour and the children painted their imaginary little boots for Saint Nicholas Day. This activity made it possible to inspire their imagination and the colour greatly roused their playfulness and curiosity. The goal of this final thesis is to show how the children experienced painting with two different techniques and whether those techniques were suitable for the topics, i.e. whether the technique influenced the topic. Even though those techniques are the most common ones in kindergarten, i.e. most used, the children experience them differently each time because with new motivation come new ideas.
